IMPROVEMENT IN POST-OFFICE LETTER-CASES.

Specification forming part of Letters Patent No. 125,606, dated April 9,1872.

To all whom it may concern:

Be it known that I, ALLEN F. MILLER, of Galva, in the county of Henryand State of Illinois, have invented certain new and useful Improvementsin Post-0fce Files; and do hereby declare the following to be a full,clear, and exact description thereof, reference being had to theaccompanying drawing and to the letters of reference marked thereon.

The nature of my invention consists in a circular revolving post-officefile, divided vertically in two parts hinged together on one side, andhaving boxes or pigeon-holes arranged cireumferentially in tiers ofsufficient number to give one box or pigeon-hole to each letter of thealphabet in each tier; and, also, in each vertical row formed by saidtiers, all having the letters of the alphabet marked upon them, in theorder hereinafter described.

In order to enable others skilled in the art to which myinventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing which formsa part 4of this specification, and in which- Figure l is a sideelevation of my device complete.- Figure 2 is a plan view of the foot orbase with the bottom rim, and Fig. 3 is a horizontal section through oneof the tiers.

A represents the base or pedestal, made in any desired manner and of anysuitable dimensions. In this base is lixed an upright shaft or pivot, B,which passes through the center of a cross-bar, D, in a circular rim, C.For better security and convenience this shaft should extend up as highas the entire file, and pass through a similar cross-bar in the top rimC. Between the two rims, C and C', are arranged twenty-six tiers ofboxes or'pigeon-holes, e e, each tier having twenty-six of such boxes orpigeon holes. On the outer circumference of the upper rim C are marked,stamped, or in any suitable manner affixed, the twentysix letters of thealphabet, in their 'regular order, and corresponding with the twenty-sixvertical rows of boxes formed bythe tiers. Upon each box or pigeon-holein each of said twenty-six vertical rows is then marked in regular orderwith a letter of the alphabet, with the top letter immediately behindit. For instance, the top box of the row marked A on the top rim, hasthe letters A A on it; the second, B A; the third, G A 5 the fourth, DA, and so on downward. The other twenty-live rows are marked in asimilar manner, substituting the top letter, whatever that may be, forthe common letter A in the above example. This arrangement of apost-office file will give seven hundred and seventy-six boxes orpigeon-holes in a convenient and compact form, so that mailmatter may bereadily distributed and delivered. This post-office le is bisectedvertically, and the two parts hinged together, so that for distributionthe file may be opened and the person distributing the mail may stand inthe center, and put the mail-matter in the boxes or pigeon-holes fromthe inside. The boxes are lettered on the inside the same as on theoutside.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

A cylindrical-revolving post-office le, when divided vertically intwoparts hinged together on one side, and having the letters of thealphabet arranged at both ends of the pigeon-holes or boxes,substantially in the manner and for the purposes herein set forth.

ALLEN F. MILLER.
